Summary
This document provides the public with notice that, on October 12, 2026, the Denton County Transportation Authority (DCTA) submitted a request for amendment (RFA) to its FRA-approved Positive Train Control Safety Plan (PTCSP) to transition to an integrated dispatch system. The purpose of the transition is to eliminate the need for DCTA dispatch personnel to operate two separate workstations and dispatch systems to perform Centralized Traffic Control (CTC) and Enhanced Automatic Train Control (E-ATC) Temporary Speed Restriction (TSR) operations. As this RFA may involve a request for FRA's approval of proposed material modifications to an FRA-certified positive train control (PTC) system, FRA is publishing this notice and inviting public comment on DCTA's RFA to its PTCSP.
